Will G.703/RJ45 handoff work for a WIC2-2MFT-T1/E1?

We've ordered a 2811 with a WIC2-2MFT-T1/E1 for an office in Chile. The LEC has indicated that they will have a G.703/RJ45 120 ohm handoff for the E1 they are delivering. Will this WIC work with this handoff. I hesitate because I was expecting RJ48.
